MIKE11 DHI – MAIN FEATURES
The software MIKE 11 (DHI) allows to simulate:
• open channel flow and floods in surface waters (rivers, streams, channels, etc.)
• unsteady flow conditions and dynamics of water quality (BOD, NH4, DO) along the modelled river
• solid transport and fluvial morphology (erosion - sedimentation)
• “Dam break” effect scenarios and flood events forecast in real time

The river model has two secondary branches, the TIRANES river (22 km) and the LANA River (23 km), and one main river, the ISHEM, with a length of 35 km.

MOUSE-MIKE11 Integration
• The OUTLETS and CSOs modelled in MOUSE were considered as point sources of pollution to the river (boundary conditions)
• MOUSE results (COD, NH4 and TSS) were imported into MIKE 11

Conclusions
• Tirana sewer system discharges a big amount of polluters in the surrounding receiving waters both in dry weather and in wet weather.
• The total flow discharged in wet weather during 4 hours (5Y 60’) is comparable with the total foul water produced during 24 hours in dry weather (500.000 eq.inh.).
• River Lana is the most critical branch due to the low flow and the high discharge.
• Improvements will be achieved with the following works:– building of the waste water treatment plant – restructuring and control of combine sewer overflows– Implementation of a continuous monitoring system of flow,
rain and water quality
